How is the flow rate of magnetic slurry measured?
Release time:
2025-11-26
Challenge:
Because commonly used electromagnetic flowmeters or Doppler ultrasonic flowmeters cannot overcome the challenges posed by magnetic slurry flows, the magnetic particles in magnetite cause significant and irregular deviations in the measurement results of magnetic flowmeters due to fluctuations in magnetic field strength, making compensation impossible.
Doppler ultrasonic flowmeters struggle to maintain high accuracy and stability over the long term. When the slurry contains large particles, abrasion can cause electrode failure and pipeline leaks, compromising measurement performance. Such malfunctions necessitate unscheduled maintenance and component replacement, thereby increasing production costs.
Solution:
Using the Prasen SONARtrac flowmeter, which employs non‑contact, passive sonar technology, delivers precise, stable measurements while extending the instrument’s service life and reducing costs. It is unaffected by variations in physical properties such as solids content, magnetism, or temperature, eliminating the need for shutdowns or recalibration. When a pipeline is replaced or dismantled, the flowmeter can be easily removed and reinstalled on the new pipe, or readily clamped onto an existing operating pipeline.
Suitable for pipelines made of various materials, including steel, ceramic-lined, rubber-lined, PVC, HDPE, and steel–rubber composite pipes. An increasing number of customers are using SONARtrac flow meters to replace ultrasonic and electromagnetic flow meters for monitoring applications such as cyclone feed lines, cyclone overflow lines, mill feed lines, mill discharge lines, concentrate lines, and tailings lines.
